RE: Unapproved and Misbranded Products Related to Coronavirus Disease 2019 (COVID-19)

This is to advise you that the United States Food and Drug Administration (FDA) and the Federal Trade Commission (FTC) reviewed your website at the Internet address www.n-ergetics.com in February 2020. The FDA has determined that your website offers colloidal silver products for sale in the United States and that these products are intended to mitigate, prevent, treat, cure or diagnose COVID-191 in people. FDA has determined that these products are unapproved new drugs sold in violation of section 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 355(a). Furthermore, these products are misbranded drugs under section 502 of the FD&C Act, 21 U.S.C. 352. The introduction or delivery for introduction of these products into interstate commerce is prohibited under section 301(a) and (d) of the FD&C Act, 21 U.S.C. § 331(a) and (d).

The Secretary of Health and Human Services, under section 319 of the Public Health Service Act, 42 U.S.C. § 247d, has determined that a public health emergency exists nationwide as a result of confirmed cases of COVID-19. Therefore, FDA is taking urgent measures to protect consumers from certain products that, without approval or authorization by FDA, claim to mitigate, prevent, treat, diagnose, or cure COVID-19 in people. As described below, you sell products that are intended to mitigate, prevent, treat, diagnose or cure COVID-19 in people. We request that you take immediate action to cease the sale of such unapproved and unauthorized products for the mitigation, prevention, treatment, diagnosis, or cure of COVID-19.

Some examples of the claims on your website that establish the intended use of your products and misleadingly represent them as safe and/or effective for the treatment or prevention of COVID-19 include:

• “Coronavirus 2019-NCoVat, Treatment Has A Home Remedy. This Chinese Wuhan Flu Pneumonia has a non-traditional remedy that has successfully killed coronaviruses from the flu virus to pandemic diseases, in vitro, for over 100 years. . . . If colloidal silver has killed coronavirus strains in past laboratory test, then the current coronaviruses should also be killed. Protect your immune system try Colloidal Silver 1100 PPM Immune Support”

• “The seven coronaviruses that can infect people are: Common human coronaviruses 1. Human coronavirus 229 E (alpha coronavirus) . . . 2. Human coronavirus NL 63 (alpha coronavirus) or HCoV-NL 63 . . . 3. Human coronavirus HCoV-OC 43 (beta coronavirus) (and HCoV-229E,) . . . 3. Human coronavirus HKU1 (beta coronavirus) . . . and a novel coronavirus, coronavirus HKU1 (CoV-HKU1) . . . 4. Human coronavirus MERS-CoV (beta coronavirus) . . . 5. Human coronavirus SARS-CoV (beta coronavirus) . . . 6. Human coronavirus 2019 Novel (never seen before) Coronavirus (2019-nCoV) (beta coronavirus) is a virus (more specifically, a coronavirus) . . . The virus has made the gigantic mutation of now infecting human to human making it one of the most dangerous pandemic viruses. . . . Colloidal Silver is still the only known anti-viral supplement to kill all seven of these Human Coronaviruses.”

• “Preventing The Contraction Of The Novel Coronavirus is Elementary. . . . Even though there are no vaccines available to combat these coronaviruses, there is a home remedy of Colloidal Silver 100 ppm that has worked effectively on coronaviruses successfully for the last 123 years. . . . In the mean time (sic) there are some tips to prevent contracting the coronavirus: . . . Use Home remedy, Colloidal silver 1100 PPM, to support immune system”

• “What is Coronavirus Treatment and Prevention? . . . Colloidal silver 1100 PPM, Home remedy for 123 years! (testing showed every known coronavirus killed in 4 min. in vitro) . . . Although there are 650,000 deaths a year from enfluenza, (sic) the regular flu and infects over 2,000,000 deaths from pneumonia a year, these two viruses pale in comparison to the potential danger to the coronavirus flu. It is very contagious and quick to kill. Colloidal Silver kills all viruses.”

You should take immediate action to correct the violations cited in this letter. The violations cited in this letter are not meant to be an all-inclusive list. It is your responsibility to ensure that the products you sell are in compliance with the FD&C Act and FDA's implementing regulations. We advise you to review your websites, product labels, and other labeling and promotional materials to ensure that you are not representing your products for a COVID-19 related use for which they have not been approved by FDA and that you do not make claims that misbrand the products in violation of the FD&C Act. Within 48 hours, please send an email to COVID-19-Task-Force-CDER@fda.hhs.gov describing the specific steps you have taken to correct these violations. Include an explanation of each step being taken to prevent the recurrence of violations, as well as copies of related documentation. Failure to immediately correct the violations cited in this letter may result in legal action, including, without limitation, seizure and injunction.

FDA is advising consumers not to purchase or use certain products that have not been approved, cleared, or authorized by FDA and that are being misleadingly represented as safe and/or effective for the treatment or prevention of COVID-19. Your firm will be added to a published list on FDA's website of firms and websites that have received warning letters from FDA concerning the sale or distribution of COVID-19 related products in violation of the FD&C Act. This list can be found at http://www.fda.gov/consumers/health-fraud-scams/fraudulent-coronavirus-disease-covid-19-products. Once you have taken corrective actions and such actions have been confirmed by the FDA, the published list will be updated to indicate that your firm has taken appropriate corrective action.

If you cannot complete corrective action within 48 hours, state the reason for the delay and the time within which you will complete the corrections. If you believe that your products are not in violation of the FD&C Act, include your reasoning and any supporting information for our consideration.

If you are not located in the United States, please note that products that appear to be misbranded or unapproved new drugs are subject to detention and refusal of admission if they are offered for importation into the United States. We may advise the appropriate regulatory officials in the country from which you operate that FDA considers your product(s) listed above to be unapproved and misbranded products that cannot be legally sold to consumers in the United States.

Please direct any inquiries to FDA at COVID-19-Task-Force-CDER@fda.hhs.gov.

In addition, it is unlawful under the FTC Act, 15 U.S.C. 41 et seq., to advertise that a product can prevent, treat, or cure human disease unless you possess competent and reliable scientific evidence, including, when appropriate, well-controlled human clinical studies, substantiating that the claims are true at the time they are made. To make or exaggerate such claims, whether directly or indirectly, through the use of a product name, website name, metatags, or other means, without rigorous scientific evidence sufficient to substantiate the claims, violates the FTC Act.

There currently are no vaccines, pills, potions, lotions, lozenges or other prescription or over-the-counter products available to treat or cure coronavirus disease 2019 (COVID-19). Thus, the claims cited above are not supported by competent and reliable scientific evidence. You must immediately cease making all such claims. In addition, you are advised to review all claims for your products and immediately cease making claims that are not supported by competent and reliable scientific evidence. Violations of the FTC Act may result in legal action seeking a Federal District Court injunction and an order may require that you pay back money to consumers. Within 48 hours, please send an email to Richard Cleland, Assistant Director of the FTC’s Division of Advertising Practices, via electronic mail at rcleland@ftc.gov describing the specific actions you have taken to address the FTC’s concerns. If you have any questions regarding compliance with the FTC Act, please contact Mr. Cleland at 202-326-3088.
